“…The results of similar works from literature are equally presented for comparison. 41–45 The kinematic viscosities of all the blends of African pear seed oil methyl ester (APSOME) with petrodiesel were all found to be higher than the fossil-diesel and within the range (1.9–6.0 mm 2 /s) needed for optimum functioning of the diesel engines. Therefore, there would be no tendency of the fuel blends giving any fuel injection flow challenges.…”

Reports on the optimum brake-power, surrogate fuel, engine emissions, and efficiency using hybrid model on high compression ratio diesel engines are very imperative for effective application of biodiesel in power and renewable energy generation. This study presents Dyacrodes edulis biodiesel engine performance and combustion release optimization using response surface methodology-genetic algorithm (RSM-GA) as well as the variation of key engine efficiency and exhaust release indices with brake power and fuel blend in a high compression ratio (CR) diesel engine. Combustion emission impacts of the blends with respect to petro-diesel decreased in values except for NOX. Brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), brake mean effective pressure (BMEP), volumetric efficiency, and exhaust temperature increased with brake power while specific energies decreased with load. Optimum conditions obtained using integrated RSM-GA were 40.03%, 0.05 kg/kW-h, 0.03%, 132.30 ppm, and 18.84 ppm for BTE, BSFC, CO, NOx, and HC respectively at low factor (engine load, engine speed, and fuel blend) conditions. At the optimum conditions, the experimental validation results were 44.01%, 0.05 kg/kW-h, 0.04%, 130.05 ppm, and 20.33 ppm for BTE, BSFC, CO, NOx, and HC respectively. The application of the feedstock in compression ignition engine is viable.

“…To improve the lower BTE due to the lower heating value of biodiesel, the author recommends advancing injection timing to improve the BTE of biodiesel. Teoh et al [172] investigated the effect of Moringa oil biodiesel (MOB) and diesel blends (10,20,30, and 50% by volume) in a multi-cylinder high-pressure common rail diesel engine. The results shown in Figure 13 indicate that the BTE of MOB is generally close to that of standard diesel at 1500 rpm.…”

“…They explained this phenomenon due to the presence of more saturated fatty acids in biodiesel, and the lower heating value of biodiesel causes lower peak temperatures, thus decreasing NO x emissions. However, Teoh et al [172] observed increased NO x emissions in a common-rail diesel engine fueled with Moringa oleifera biodiesel (MOB) and diesel blends. Figure 28 shows the results of NO x emissions at different engine speeds and different ratios of biodiesel.…”

Due to the increasing air pollution from diesel engines and the shortage of conventional fossil fuels, many experimental and numerical types of research have been carried out and published in the literature over the past few decades to find a new, sustainable, and alternative fuels. Biodiesel is an appropriate alternate solution for diesel engines because it is renewable, non-toxic, and eco-friendly. According to the European Academies Science Advisory Council, biodiesel evolution is broadly classified into four generations. This paper provides a comprehensive review of the production, properties, combustion, performance, and emission characteristics of diesel engines using different generations of biodiesel as an alternative fuel to replace fossil-based diesel and summarizes the primary feedstocks and properties of different generations of biodiesel compared with diesel. The general impression is that the use of different generations of biodiesel decreased 30% CO, 50% HC, and 70% smoke emissions compared with diesel. Engine performance is slightly decreased by an average of 3.13%, 89.56%, and 11.98% for higher density, viscosity, and cetane, respectively, while having a 7.96% lower heating value compared with diesel. A certain ratio of biodiesel as fuel instead of fossil diesel combined with advanced after-treatment technology is the main trend of future diesel engine development.

“…Raw Moringa oleifera oil was converted into Moringa oleifera methyl ester using two-stage transesterification process. As acid value of raw oil was high, two stage esterification process was performed [4] , [5] , [6] . Acid esterification was carried out using 6:1 methanol to oil ratio with the addition of 0.5 (w/w) of H 2 SO 4 to preheated oil [2] , [3] .…”

The present data article is based on the research work which investigates the effect of cetane enhancer on thermally coated engine fuelled with Moringa oleifera methyl ester (MOME) . In this experimental work, Kirloskar TV1 model direct injection water cooled diesel engine with eddy current dynamometer was used. MOME was produced by two-stage transesterification process. The physio-chemical properties of Moringa oleifera methyl ester (MOME) were analysed based on American Standards for Testing Materials (ASTM) standards and data's were presented. Further, the fuel properties were enhanced with the addition of 1% of cetane enhancer (namely Pyrogallol) to MOME and data's related to improved fuel properties were presented. Engine was loaded from minimum load to maximum load using eddy current dynamometer. The combustion chamber components such as piston head, cylinder head and intake and exhaust valves were coated with Yttria Stabilized Zirconia (YSZ) to transfigure the normal engine into low heat rejection engine. Engine tail pipe emissions were determined using AVL, Austria make 444 di-gas analyser and AVL, Austria make 437C smoke meter equipment. Data related to fuel samples like diesel, MOME with and without Cetane enhancer in normal and ceramic engines were presented.
